Lake Daugherty Upground Reservoir dam
Lake Daugherty Upground Reservoir
Lake Daugherty Upground Reservoir, also known as Fostoria Reservoir No. 1, is a significant water supply source located in Hancock, Ohio. Built in 1891, this earth dam stands at a height of 12 feet and stretches 3500 feet in length, providing a storage capacity of 141 acre-feet. With a normal storage capacity of 125 acre-feet and a surface area of 11 acres, this reservoir plays a crucial role in meeting the water supply needs of the local community.
Managed by the local government and regulated by the Department of Natural Resources in Ohio, Lake Daugherty Upground Reservoir is inspected every five years. Despite its historical significance, the reservoir's condition has been assessed as poor, indicating a need for maintenance and potential improvements. With a hazard potential classified as significant, there is a heightened focus on emergency preparedness and risk management measures to ensure the safety and security of the dam and surrounding areas.
As an essential water resource in the region, Lake Daugherty Upground Reservoir serves as a vital component of the local infrastructure. Its strategic location along the East Branch Portage River supports water supply needs while also presenting challenges that require ongoing monitoring and management. Enthusiasts interested in water resources and climate will find this reservoir to be a fascinating case study in balancing water supply demands with the need for critical infrastructure maintenance and risk mitigation strategies.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.
Plan around the weather

About Lake Daugherty Upground Reservoir
Where does the data for Lake Daugherty Upground Reservoir come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
